Specifications

The RR1220P series features a power rating of 0.1W. The '4021' in the part number indicates a resistance of 4.02 kΩ. The 'B' signifies a tight tolerance, usually ±0.1%. The 'T5' likely refers to packaging details specific to Susumu's manufacturing process. The TCR is typically low, such as ±25 ppm/°C. The operating temperature range is generally between -55°C and +155°C.

Susumu utilizes thin film technology, depositing a thin layer of resistive material on a ceramic substrate, which contributes to the resistor's stability and precision. The RR1220P-4021-B-T5 offers excellent long-term reliability, making it suitable for critical applications where accurate and stable resistance is required. The 1206 package size allows for efficient use of board space, while the low TCR minimizes the impact of temperature fluctuations on resistance value.
