Littelfuse Unveils SSA Series Current Shunt Resistor Solution for High-Performance Current Sensing
Littelfuse, an industrial technology manufacturing company empowering a sustainable, connected, and safer world, announced the launch of its SSA Series Current Shunt Resistors—the first of its kind in the Littelfuse portfolio. These two-terminal, ultra-low resistance shunt resistors are uniquely designed to meet the increasing demand for accurate current measurement in high-performance applications.
Unlike competing technologies such as Hall effect sensors, current transformers, flux gate sensors, and Rogowski coils, the Littelfuse Current Shunt Resistor delivers a more efficient solution that works well in both AC and DC circuits. With a higher power rating than metal foil resistors, the SSA Series excels in applications demanding rigorous current sensing due to high-power requirements.
This versatility makes it an ideal choice for a wide range of markets and applications, including:
●automotive electronics,
●EV charging,
●large appliances,
●data centers,
●industrial,
●power modules, and
●frequency converters.
“Accurate current measurement is crucial for the optimal performance of electrical and electronic devices," says Stephen Li, Product Manager at Littelfuse. "With the ever-increasing demand for high-performance devices, our SSA Series Current Shunt Resistors offer a cost-effective solution for both AC and DC applications requiring demanding current sensing.”
The Series offers the following key features and benefits:
●Cost-effective: More affordable than competing technologies.
●Versatility: Compatible with both AC and DC circuits.
●Compact Size: Ideal for space-constrained applications.
●Good Heat Dissipation: Ensures reliable performance.
●English Case Sizes: Available in 2512, 3921, and 5931.
●Resistance: Range from 0.2 – 4.0mΩ.
●Power Rating: Up to 15W.
●Tolerance: As low as ±1.0%.
●TCR: Down to ±50ppm/℃.
Availability
The SSA Series Current Shunt Resistors are available in tape-and-reel quantities of 3,000. Place sample requests through authorized Littelfuse distributors worldwide.
