  • Clamping Voltage

    Clamping voltage is a term used in electronic components, particularly in devices like diodes and transient voltage suppressors. It refers to the maximum voltage level at which the component can effectively limit or clamp the voltage across its terminals. When the voltage across the component exceeds the clamping voltage, the component conducts and effectively limits the voltage to that level, protecting the circuit from overvoltage conditions. Clamping voltage is an important parameter to consider when selecting components for applications where voltage spikes or surges may occur, as it determines the level at which the component will start to protect the circuit.

    4.5kA
  • Capacitance @ Frequency

    Capacitance @ Frequency refers to the value of capacitance that a capacitor exhibits when subjected to an alternating current (AC) signal at a specific frequency. This parameter highlights how the capacitor's behavior changes with frequency, as capacitance can vary due to effects like equivalent series resistance (ESR) and loss factors. Typically measured in microfarads (µF) or picofarads (pF), this value is crucial for applications involving signal coupling, filtering, and timing where AC signals are prevalent. Understanding capacitance at different frequencies helps in selecting the right capacitor for specific circuit functions.

    420pF @ 1kHz
  • Varistor Voltage (Max)

    The parameter "Varistor Voltage (Max)" refers to the maximum voltage that a varistor can withstand without breaking down. A varistor is a type of electronic component that is used to protect circuits from overvoltage conditions by rapidly changing its resistance in response to voltage fluctuations. When the voltage across a varistor exceeds its maximum rating, it will conduct current and dissipate the excess energy as heat, thereby protecting the circuit. It is important to select a varistor with a maximum voltage rating that is higher than the expected operating voltage to ensure reliable protection against overvoltage events.

    517V
  • Energy

    In electronic components, "Energy" refers to the amount of electrical power consumed or stored by the component during operation. It is a crucial parameter that determines the efficiency and performance of the component. Energy consumption is typically measured in units such as watt-hours (Wh) or joules (J), while energy storage is often quantified in terms of capacitance or battery capacity. Understanding the energy characteristics of electronic components is essential for designing efficient and reliable electronic systems.

  • Varistor Voltage (Min)

    Varistor Voltage (Min) is the minimum voltage at which a varistor begins to conduct significantly and clamp voltage spikes. It is a critical parameter as it indicates the threshold for the protective action of the varistor. When the voltage exceeds this level, the varistor transitions from a high-resistance state to a low-resistance state, providing a path to divert excess current. This feature helps protect electronic circuits from transient voltage surges.

    423V
  • Varistor Voltage (Typ)

    The parameter "Varistor Voltage (Typ)" in electronic components refers to the typical voltage at which a varistor begins to conduct significantly. A varistor is a type of voltage-dependent resistor that is commonly used to protect electronic circuits from voltage spikes and surges. When the voltage across a varistor exceeds its varistor voltage, the device starts to conduct and shunt the excess voltage to protect the circuit. The "Typ" designation indicates that the specified voltage is a typical value, and actual varistor voltages may vary slightly within a specified range. Understanding the varistor voltage is crucial for selecting the appropriate varistor for a given application to ensure effective protection against voltage transients.

    470V
  • Maximum AC Volts

    Maximum AC Volts is a parameter that specifies the maximum voltage level that an electronic component can safely handle when operating with an alternating current (AC) input. This parameter is crucial for ensuring the component's reliability and longevity, as exceeding the maximum AC voltage can lead to damage or failure. It is typically expressed in volts and is determined through testing and analysis of the component's electrical characteristics. Designers and engineers must carefully consider the maximum AC volts rating when selecting components for a circuit to prevent overloading and potential hazards.

    300V
  • Varistor Voltage

    A varistor is an electronic component that is used to protect circuits from overvoltage conditions. The varistor voltage, also known as the "clamping voltage" or "breakdown voltage," is the voltage level at which the varistor begins to conduct significantly and divert excess current away from the circuit. When the voltage across the varistor exceeds its varistor voltage, the varistor's resistance decreases rapidly, allowing it to absorb the excess energy and protect the circuit components. Varistor voltage is an important parameter to consider when selecting a varistor for a specific application, as it determines the level of overvoltage protection provided by the component.

    470V
  • Maximum DC Volts

    Maximum DC Volts is a parameter that specifies the maximum voltage that an electronic component can safely handle when operating with direct current (DC) power. This value is crucial for ensuring the component's longevity and preventing damage due to overvoltage. Exceeding the maximum DC voltage rating can lead to permanent damage or failure of the component. It is important to carefully consider this parameter when designing or selecting electronic components for a circuit to ensure proper functionality and reliability.

    385V
  • Current - Surge

    The parameter "Current - Surge" in electronic components refers to the maximum current that a component can handle for a short duration without being damaged. Surge current is typically higher than the component's rated continuous current and is often associated with transient events such as power surges or inrush currents during startup. It is important to consider the surge current rating when designing or selecting components to ensure they can withstand sudden spikes in current without failing. Exceeding the surge current rating can lead to overheating, component damage, or even system failure.

    4.5kA
