High Voltage MELF Resistors WRM-HV Series General Note TT Electronics reserves the right to make changes in product specification without notice or liability. All information is subject to TT Electronics’ own data and is considered accurate at time of going to print. © TT Electronics plc BI Technologies IRC Welwyn www.ttelectronics.com/resistors 01.25 Electrical Data Features:
- High limiting element voltage up to 1kV
- 1.2/50µs surge voltage to 6kV
- Tolerance down to 0.1%
- TCR down to 25ppm/°C
- AEC-Q200 All parts are Pb-free and comply with EU Directive 2011/65/EU amended by (EU) 2015/863 (RoHS3) Physical Data Construction A metal film is deposited onto a high dissipation ceramic former to which tin plated terminating caps are fitted. The resistor is adjusted to value by a helical cut in the film and the body is protected by a lacquer coating. Marking Resistance values are colour coded with three or four bands, indicating value and multiplier. Terminations Material Plated steel cap Solderability The pure tin finish produces ageing free contacts on which low melting solders can be used. Dipped area shall be covered with a smooth and bright solder coating after 3 seconds immersion at 215°C. Solvent Resistance The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuit boards.
