TT electronics plc’s (Patterson, NJ) IRC Inc. (Boone, NC) Wirewound and Film Technologies division announced a new resistor family that includes devices capable of handling continuous voltages up to 3,000V. Designated the HVC Series, the thick-film, surface-mount resistors exhibit good power and voltage-handling capabilities, making them suitable for use in power supplies, circuit breakers, lighting controls and other high-voltage applications.
The HVC Series resistors are offered with limiting element voltages of 1,000V, 2,000V and 3,000V in 1206, 2010 and 2512 industry-standard chip sizes, respectively. Power ratings for the three chip sizes range from 0.3W to 1W at 70 degrees C. Resistance values range from 100 kiloohms to 1 gigaohm, with tolerances down to 0.5 percent and TCRs to 100ppm/C. The operating temperature ranges from –55 to +150 degrees C.
With thick-film construction and wrap-around terminations to prevent leaching, the HVC Series resistors can be immersed in 260 degrees C solder for 30 seconds, enabling the resistors to be mounted on one side of a PC board while leaded components are attached to the other side. The resistors are fully compatible with high-speed placement equipment and all types of soldering processes.
Typical pricing for the HVC Series resistors ranges from $0.20 to $1.50 based on production volumes. Lead times are from stock to 8 to 10 weeks.
