Mini Solder Sleeve Discrete Wire Terminals

Application

The SD Series streamlines the termination of discrete wires to pins, posts, and tabs. Featuring an all-in-one design, it integrates a precise solder preform, flux, and an adhesive-lined heat-shrink sleeve. A single heating step creates a fully soldered, sealed, and insulated connection, eliminating the variability of manual soldering. The shrunk sleeve provides mechanical reinforcement to protect against vibration and pull-out. Ideal for high-density applications in automotive connectors, motor leads, and relay terminals.

Series Overview

• SD125B: For applications up to 125 °C requiring the solder rings to meet environmental protection requirements compliance; provides standard sealing and is suitable for most electronic harnesses and pin/tab connections. 

• SD125C: For applications up to 125 °C where the solder rings environmental protection requirements is not required; standard sealing performance for general wire-to-pin/post/tab joints. 

• SD150A: For high-temperature environments up to 150 °C; delivers robust sealing and soldering for demanding or elevated-temperature applications.

Features and Benefits

• 3-in-1 Efficiency: Solders, insulates, and seals in a single, streamlined operation.

• Visual Inspection: Transparent sleeve enables immediate, non-destructive verification of the joint quality.

• Process Consistency: Controlled solder preforms ensure repeatable integrity, eliminating cold joints.

• Wide-Temp Reliability: Delivers long-term moisture and corrosion protection across -55°C to 150°C (depending on series).

Product Specifications

Note: Cadmium-free option is available for operating temperature of 125℃ [257]. Consult DINGYUAN for details.

Note: SD series are used for attaching leads smaller than 26AWG (0.15 mm²) to terminals less than 0.6 [.025] wide. 

*The SD150A-063 and SD150A-217 are primarily for single wire termination and do not have a wire stop. The SD150A-41XX series will accept either one or two wires;the parts have a built-in wire stop that will locate the wire approximately 0.76[0.03] from bottom of terminal. 

**Minimum. Wire insulation must be smaller than this. When using the SD150A-41XX parts for two-wire terminations, the combined wire insulation diameters must be less than 1.5[.060]. 

†Maximum. The combination of conductor diameter and terminal width, and the wire insulation must be greater than this. 

††The terminal length should be at least 1.2[0.05] shorter than this.The wire strip length must be adjusted so that, when terminated, the exposed conductor is covered by the sleeves.
