THICK FILM NETWORK RESISTOR FRM % # B49

Category: Electronics, Fenghua Advanced Technology, Resistors

Product Overview

The datasheet presents information on thick film network resistors, which are part of a product line referenced as ‘FRM % # B49’. These resistors are designed in a miniature form for high-density assembly applications, ensuring stable electrical capabilities and high reliability. The document highlights the flexibility in resistance value combinations available to tailor to various requirements.

Ordering Information

Details for placing orders are provided under the ‘HOW TO ORDER’ section. The circuit code, number of pins, pin distance, resistance value codes, and resistance tolerance are all customizable elements that can be specified when ordering. The standard pin distance is either 2.54mm or 1.778mm, while resistance values and tolerance adhere to certain industry codes expressed in a three-digit format, where the first two digits represent significant figures and the third denotes the number of zeros for certain types, or follows a different scheme for other types described in the datasheet.

Construction and Dimensions

The construction of the resistor includes an outer coating, a conductor, and a ceramic substrate. Standard and special dimensions are highlighted, as well as dimensions related to resistance/protection coating, which changes depending on the type (Type T or Type B) of the resistor chosen. Specific measurements are given for the lead pins and the overall size, including the length and diameter, with tolerances included for precise engineering requirements. A note indicates that the first pin on the resistor is designated with a white dot for easy identification.

Resistance Value and Tolerance Coding

Resistance values are denoted by codes that follow the E-24 series for significant figures and quantity of zeros. Tolerance is indicated by a separate code and includes common tolerances like 1%, 2%, and 5%. There is a mention of a jumper (possibly a zero-ohm link), denoted by a different code.

Design Considerations

Given the need for stable electrical capabilities and high reliability, these components are likely aimed at precision electronic applications. The detailed coding and customizable options suggest a product line intended for a range of industrial or commercial uses where variations in resistance and tolerances are critical for circuit design.
