Panasonic Industry supplies a choice of resistors for applications which require high reliability or high power capability.
The ERA series of thin-film chip resistors are a high-reliability type of resistor. They offer stable performance at high temperature and high humidity: resistance change is far less than 0.1% after 1,000 hours of testing at a temperature of 85°C and 85% relative humidity.
These resistors are also notable for their high accuracy over their operating-temperature range of -55°C to 155°C. Resistance tolerance can be as low as ±0.05%. The ERA series devices also offer low current noise and excellent linearity.
There are five series of ERA resistors:
- ERA 1A: 0201 package, 0.05W power rating
- ERA 2A: 0402 package, 0.063W power rating
- ERA 3A: 0603 package, 0.1W power rating
- ERA 6A: 0805 package, 0.125W power rating
- ERA 8A: 1206 package, 0.25W power rating
Panasonic Industry also offers the ERJ B series of high-power chip resistors, a wide-terminal type. These resistors are for automotive electronic circuits and current sensing in power supplies. They feature high solder-joint reliability and excellent heat dissipation thanks to their wide terminals.
The ERJ D series of high-power chip resistors, also a wide-terminal type, are notable for their low temperature coefficient of resistance of ±100×10-6/°C.
