Cement-coated wire wound resistors ZDSA

Product catalog summary

Overview:
This technical document provides detailed specifications and ordering information for cement-coated wire-wound resistors with spot-welded radial tabs and adjustable lugs, produced by KRAH-RWI Elektronische Bauelemente GmbH. The resistors conform to DIN 44192 standards and are available in various sizes and power ratings.

1. Product Description

The resistors are cement-coated wire-wound types with spot-welded radial tabs. Adjustable lugs (Abgreifschelle) are provided for mounting. Variants with cross-type profiles are available upon request. Tabs labeled 'P' are cement-underlaid and solderable.

2. Standards and Models

Standards: DIN 44192 compliance for resistor sizes.
Models: ZDSA and ZDRS series, differentiated by profile and tab configurations.

3. Electrical Specifications

Resistance Range: From 1 Ω up to several hundred kilo-ohms (e.g., 1 R 1 to 620 K).
Resistance Tolerances: ±5% (J) and ±10% (K) options.
Power Ratings: Range from 20 W up to 300 W depending on size and model.
Dissipation at Various Conditions: Power dissipation values are provided for different operating temperatures (40°C, 70°C) and heat conditions (200°C, 300°C, 350°C).
Limiting Voltage: Up to 3000 V depending on resistor size.

4. Mechanical Specifications

Dimensions: Detailed dimensions in millimeters for each resistor size, including length (L), diameter (D), tab dimensions (e, b, c), and maximum allowable tolerances.
Profiles: Ceramic profiles 1 and 2 are available, with specific dimensional data.
Tabs: Various tab types (P, S, E) with corresponding dimensions and mounting options.

5. Ordering Information

Example order code: "100 Stück ZDSA-P 1 24 x 165 - 10 R J" indicating quantity, model, tab type, size, resistance value, and tolerance.

6. Additional Notes

Non-inductive resistor versions (“Ni”) are available; refer to separate product descriptions.
Resistors with cross-profile are available on request.
Power ratings and dissipation values vary with temperature and heat conditions; users should select appropriate ratings based on application environment.
