1004

Overview

The Visaton GmbH & Co. KG model 1004 is a fixed resistor belonging to the D-AP series, manufactured by Vishay. It is a rectangular chip resistor constructed with metal glaze on high-quality ceramic, designed for conductive gluing applications. The component features AgPd terminations and operates within a temperature range of -55 °C to +155 °C. It has a rated dissipation of 0.25 W and a limiting element voltage of 50 V. The resistance value is 4750 Ω with a tolerance of ±1%. The package size is 1206 (3.2 mm x 1.6 mm), and it complies with RoHS directives.

Feature Summary

• Designed specifically for conductive gluing processes utilizing AgPd terminations
• Constructed with metal glaze on high quality ceramic substrate
• Provides stability with ΔR/R = 1 % for 1000 h at 70 °C

Applications

• Conductive gluing assembly in electronic circuits
• General purpose fixed resistor applications requiring specific termination compatibility

Procurement Notes

Verify the exact part number suffix against official Vishay documentation to ensure correct tolerance and packaging specifications. Confirm that the application environment does not exceed the maximum operating temperature of 155 °C or the limiting element voltage of 50 V. Ensure the manufacturing source is recognized as Vishay, as Visaton serves as a distributor identifier in some contexts.

Selection Notes

Select this component when conductive adhesive mounting is required due to its specialized AgPd terminations. The 1206 package size offers a balance between power handling and board space. Consider the ±1% tolerance requirement and the 0.25 W power rating relative to circuit load. Verify compliance with halogen-free definitions if environmental regulations apply to the final product assembly.

Part Context

This component is part of the D-AP series from Vishay Draloric, which specializes in thick film rectangular chip resistors. The series is engineered for reliability in surface mount applications where standard soldering may not be suitable or where conductive bonding is preferred. It shares the general electrical characteristics of the D-AP family but is defined by its specific resistance value and termination material.
