High Voltage Chip Resistors
(HVR)Thick-Film Chip Resistors operate at high voltages Introduction
New (HVR) High-voltage chip resistors deliver power ratings up to 4 KV. Token electronics has introduced a thick-film chip resistor series with wide resistance range from 10Ω to 100MΩ. The (HVR) series of surface mount resistors feature high-voltage operation in standard 0402, 0603, 0805, 1206, 2010 and 2512 package sizes, making them well ideal for automatic handling methods.
The (HVR) resistors offer high voltage, extended surge ratings. This pulse-withstanding chip resistors combine extended surge values with high-voltage ratings for high-power applications. The (HVR) series are designed for use in high-voltage power supplies, circuit protection devices, medical equipment (defibrillators), military equipment (night vision cameras, x-ray equipment), automotive industry, and High Pulse Equipments.
Token's (HVR) series features high grade alumina substrate wrap-around terminations with an electroplated nickel barrier (Ni) with Edge Electrode (NiCr), and either tin/lead or RoHS-compliant matte tin finish. In addition, the overall robust construction allows the chip resistor to operate in harsh, high-voltage environments.
The (HVR) series feature tolerances of ±1%, and ±5%. Continuous voltage ratings are rated up to 3 KV, with maximum overload voltage to 4 KV. Power ratings for the HVR02(0402), HVR03(0603), HVR05(0805), HVR06(1206), HVR0A(2010) and HVR12(2512) resistors are 1/16W, 1/10W, 1/8W, 1/4W, 1/2W and 1W, respectively, with an operating temperature range of -55°C to +155°C. Custom specifications are available.
The (HVR) series are available in taping packaging and RoHS compliant.
