Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
The SMS-PW space approved current sensing precision resistor series from Isabellenhütte offers SnPb tinned connections suitable for aviation and aerospace applications being ESCC 4001/027 qualified. Higher power ratings and low internal temperature rises due to the larger pad termination sizes. The MANGANIN® alloy resistance element has a resistance range of 0.003Ω to 1Ω, TCR of ±50ppm/°C at ≥0.01Ω or ±100ppm/°C at <±0.01Ω over the temperature range of +22°C to +60°C (please see the table below for further information) and offers excellent long term stability. The SMS-PW model offers these capabilities in a 2512 chip size.
