B82801 SMT Current Sense Transformers

TDK B82801 SMT Current Sense Transformers offer very low DC resistance and different turns ratios within very small, RoHS-compliant packages. The components feature a frequency range of 50kHz to 1MHz and an operating temperature range of -40°C to +125°C. An insulated coating of the ferrite cores provides space-saving installation on tightly populated boards. Highly automated production using laser welding technology ensures excellent reproducibility and high reliability.
