ROHM Introduces Ultra Low Ohmic Chip Resistors for Automotive, Consumer, and Industrial Equipment
ROHM Expands PMR100 Shunt Resistor Series: Delivering High Power and Miniaturization for Demanding Applications
BonChip Electronics, a leading distributor of electronic components, is excited to announce the expansion of ROHM Semiconductor's PMR100 series of shunt resistors. These new additions offer a significant leap forward in power handling capabilities while maintaining a compact footprint, ideal for space-constrained applications in automotive, consumer, and industrial equipment.
Shunt Resistors: A Critical Component for Precise Current Detection
Shunt resistors play a vital role in various applications by enabling accurate current detection. They are widely used for functions like power supply overcurrent protection, battery level monitoring, and motor drive circuits across diverse industries: automotive, industrial equipment, and consumer electronics. As technology advances and applications become more feature-rich, the demand for smaller, higher-power shunt resistors with exceptional precision is paramount. This is particularly true in the automotive sector, where accurate current detection is essential under demanding high-temperature conditions.
ROHM's Innovation: Unmatched Power Density in a Compact Package
The latest additions to the PMR100 series showcase ROHM's commitment to innovation. These new products achieve a remarkable 5 W rated power rating across three resistance values: 0.5 milli-ohm, 1.0 milli-ohm, and 1.5 milli-ohm. This groundbreaking advancement leverages cutting-edge materials with superior thermal characteristics and meticulous terminal temperature derating. The result? These new PMR100 resistors boast the highest power rating available for 6432-size flat chip types with protective film.
Significant Power Improvement Enables Miniaturization
These groundbreaking 5 W PMR100 resistors offer a significant advantage over their predecessors. They deliver approximately 2.5 times the power handling capacity compared to conventional 2 W PMR100 models and roughly 1.7 times higher than 3 W options. This translates to the ability to replace larger, bulkier high-power resistors, facilitating significant miniaturization across a wide range of applications.
Exceptional Performance for Extreme Environments
The new PMR100 resistors are engineered for exceptional performance even in harsh environments. They boast a guaranteed rated terminal temperature of 130°C (for 0.5 milli-ohm and 1 milli-ohm products) and an impressive operating temperature range spanning from -65°C to +175°C. This ensures stable operation and reliable current detection under extreme temperature conditions. Furthermore, these resistors feature an outstanding temperature coefficient of resistance (TCR) of ±75ppm/°C, guaranteeing high-accuracy current measurement.
ROHM's Commitment to Expanding the PMR100 Series
ROHM's dedication to continuous development extends beyond the current expansion. They are actively pursuing further advancements in both power and resistance ranges for the PMR100 series. This roadmap includes adding compact, high-power, high-temperature, high-accuracy models with 4 W ratings in even smaller sizes like 1210 and 2010.
Key Applications for the PMR100 Series
The PMR100 series finds application in a vast array of sectors, including:
- Automotive: Electric power steering (EPS), electric compressors, oil/water pumps, door motors, advanced driver-assistance systems (ADAS) controllers, and more.
- Industrial Equipment: Industrial power modules, power conditioners, power tools, photovoltaic (PV) inverters, server power supplies, uninterruptible power supplies (UPS), base station power supplies, and more.
- Consumer Applications: Home appliances such as air conditioners, refrigerators, vacuum cleaners, washing machines, and more.
