element14 is now stocking the latest Panasonic chip resistors, providing users with high power operation in compact packages.
This is a significant addition to element14’s passive component portfolio that will enable customers to substantially accelerate their new product development-to-market programmes, with full confidence in fast and reliable sourcing. Applications include inverters, battery management systems, ADAS, LiDAR, radar, lighting, onboard chargers, industrial robots and a wide range of automotive systems.
The global resistor market is demanding higher power ratings in smaller footprints to allow new designs to be optimised into smaller package sizes without compromising performance, even in the harshest environments. The new chip resistors from Panasonic offer double the power rating of conventional thick film resistors and enable design engineers to upgrade to a high-value resistor with a higher power in smaller case sizes, saving real-estate on the PCB.
Six products from the innovative Panasonic chip resistor series are now available for fast delivery from element14, including:
- ERJH* Series offers high-temperature operation with derating starting from 105⁰C helping to achieve high power while downsizing. It can achieve a maximum category temperature of 175⁰C and a rated category temperature of 105⁰C. An improvement to solder crack resistance guarantees the resistor endures 1000 cycles of thermal shock testing. The ERJH* Series features a power derating of 0.1W – 0.5W and a case size of 0402 – 0805.
- ERA*V/K Series are high accuracy resistors with high stability achieved by thin-film resistor design. Featuring a low resistance tolerance, the ERA*V/K Series offers high voltage in comparison to conventional thin-film resistors. They have a higher power rating than the current product with limiting element voltage and maximum overload voltage. Key features include high reliability, and stability at high temperatures and humidity, with a case size of 0402 – 0805.
- ERJP Series provides double with the power rating compared to conventional thick film resistors with ESD surge characteristics similar to standard metal film resistors. Heat dissipation is increased by an optimised resistance pattern while the resistance material and electrode design enable downsizing and a high-power rating of 0.20W – 0.66W. The case size is 0402 – 1210.
- ERJPM Series is a high voltage, high precision resistor series with a high power-rating compared to conventional thick film resistors. Suitable for high voltages with a limiting element voltage of 500V. The ERJPM Series features a case size of 1206 and a resistance range of 1.02M – 10MΩ.
- ERJB/D Series features wide terminal resistors, providing high solder-joint reliability with ultra-high-power ratings compared to conventional thick film resistors. Also available as a very cost-effective shunt resistor, the ERJB/D Series is suitable for small size, high power current detection with a case size of 0508 – 1020 and power rating of 0.33W – 2W.
- ERA*A Series are high accuracy resistors with high reliability achieved by thin-film resistor design. They provide high accuracy, low resistance tolerance and TCR. The high-reliability design is stable at high temperatures and humidity. The case size is 0201 – 1206.
All products in the series contribute to the size and weight reduction of new products and are AEC-Q200 compliant (except ERA*A).
