Current sensing resistors offer long-term stability

September 15, 2015 // By Graham Prophet
Panasonic Automotive & Industrial Systems adds current sensing resistors featuring ultra-low ohmic values (as low as 0.5 milliohms) and TCR values down to 75ppm.

ERJMS4 and ERJMS6 series components offer high power ratings of up to 5W and are available in different case sizes (1206 to 2526). Based on metal plate bonding technology, the parts claim excellent long term stability. The mould resin allows high heat dissipation for a wide operating temperature range of -65°C to +170°C.

The devices have been designed for industrial electronics and automotive/transportation applications, such as engine cooling fan, engine ECU, braking system, steering EPS, transmission system, etc. Comments Stephane Ngandeu Latta, Product Manager, Panasonic Device Solutions Business Division: “Our new current sensing resistors are ideal for applications where high current measurement accuracy is important and are also well suited for current detection under high current circuit (short circuit current detection). Thanks to their AEC-Q200, ISO9001, and ISO/TS16949 certifications the products adhere to the most stringent quality standards available.”
