Thick Film Network Resistor Datasheet

Category: Electronics, Fenghua Advanced Technology, Resistors

Product Overview

The subject of this datasheet is a miniature high-density Thick Film Network Resistor designed for applications requiring stable electrical capability and high reliability. These resistors are capable of being customized with combinations of different resistance values to meet the specific needs of varied electronic assemblies.

Ordering Information

To order, one must specify the product code, which includes the circuit code, number of pins, pin distance, resistance value codes, and resistance tolerance. The specified circuit code (for example, “4854164”) identifies the internal connection of the resistors within the network. The number of pins is denoted by a combination of digits (e.g., “3 1M27”), suggesting the number of resistor elements and the form factor of the network.

Resistance Value Code

The resistance value for each resistor element within the network is represented by a three-digit code (based on the E-24 series). The first two digits are significant figures, and the third digit indicates the number of trailing zeros. The datasheet specifies coding examples for different resistor types (A, B, C, D, etc.), emphasizing that tolerance is indicated separately.

Resistance Tolerance Code

Tolerance codes are provided alongside the resistance values to indicate the precision of the resistor elements. The codes are associated with standard tolerance levels (for example, “F” for ±1%, “G” for ±2%, and “J” for ±5%).

Construction and Dimensions

The Thick Film Network Resistor outlined in this datasheet consists of ceramic substrate material, conductive paths, and an outer protective coating. Dimensions are provided in millimeters, covering aspects such as the overall length, width, and height of the component, as well as pin distances and thicknesses. These dimensions are crucial for ensuring compatibility with the intended circuit board layout and the mechanical fit within end-user devices.

The datasheet emphasizes special and nominal dimensions, providing values for types T and B. These nominal dimensions outline the standard sizes while special dimensions may refer to custom sizes available upon request. Additionally, the lead pin specifications and the notation of the first pin with a white dot are listed for proper orientation during installation.
