Cement-coated wire wound resistors ZH-ZP

Product catalog summary

Overview: This document provides technical specifications for cement-coated wire-wound resistors in flat style, produced by KRAH-RWI Elektronische Bauelemente GmbH. It includes details on resistance ranges, tolerances, power ratings, and dimensions.

Specifications:

Resistance Range: The resistors are available in various resistance values, ranging from 1 Ohm to 30 Kilo-ohms.
Resistance Tolerances: Available tolerances are K (± 10%) and J (± 5%).
Power Rating: The power ratings vary depending on the model, with values such as 6.0 W, 8.0 W, 12.0 W, and 17.0 W.
Limiting Voltage: The maximum voltage ratings are 250 V, 300 V, 350 V, and 500 V, depending on the model.
Limiting Surface Temperature: The maximum surface temperature is specified as 350°C.

Dimensions: The document provides dimensions for different models, such as ZH 25, ZH 38, ZH 50, and ZH 75, with specific measurements in millimeters for length, width, and height.

Materials: The leads for ZH models are made of CuZn with silver plating, while ZP models use CuSn with tin plating.

Additional Information: Other styles and special versions are available upon request.
