SVH-21T-P1.1 Introduction

A compact but effective part made for printed circuit boards is the SVH-21T-P1.1 socket contact. It is a well-liked option for consumer electronic items because of its dependability, high-current carrying capability, and crimp termination design. This socket contact is a great option for a number of purposes, including connecting the power supply, audio equipment, and lighting controls. The technical details, design, and applications of the SVH-21T-P1.1 socket contact, as well as its installation and maintenance, will all be covered in this article.

SVH-21T-P1.1 Speciation

The maximum current rating for wire gauge #16 is 10A AC/DC, and the maximum voltage rating is 250V AC/DC for the SVH-21T-P1.1 socket contact. After environmental tests, the contact has an initial contact resistance value of 10 m and a maximum of 20 m. It can work in a temperature range of -25 °C to +85 °C. The contact can handle 1,500 VAC of standing voltage per minute and has a minimum insulating resistance of 1,000 M.

The SVH-21T-P1.1 socket contact is intended for use with printed circuit boards with a 1.6mm thickness and compatible with wire gauges ranging from #22 to #16. Tin plating is used to make contact, which helps prevent corrosion and increases its longevity even in challenging conditions. Additionally, the tin plating increases the contact’s electrical conductivity, enhancing signal transmission and minimizing signal loss.

It is crucial to remember that to avoid current imbalance or other issues, parallel current branching that exceeds the rated current should be avoided. If it is absolutely required to branch such a big current in parallel, phosphor bronze contacts should be used, and the circuits should be built so that there is a safety margin added to each circuit to prevent imbalance.

Overall, the SVH-21T-P1.1 socket contact’s technical characteristics make it a dependable and high-performing option for various applications. It can be used in various electrical circuits due to its current and voltage ratings, temperature range, insulation resistance, and contact resistance values. In addition, the contact’s tin coating and RoHS2 compliance guarantee its durability even in challenging conditions.

SVH-21T-P1.1 Design and construction

The crimp-style SVH-21T-P1.1 socket contact is made for use with printed circuit boards. It is made from a base material of tin-plated copper alloy, which offers high electrical conductivity and endurance. Because there are two points of contact on the contact, stable and dependable electrical connections are guaranteed. The probability of electrical failure is decreased thanks to this design’s efforts to reduce contact resistance.

The contact has a distinctive contact spring structure that offers a strong retention force and aids in keeping the contact from coming loose while in operation. Thanks to the spring structure, the contact may be put on and taken off of the circuit board with ease.

The contact’s crimp termination design enables quick and secure wire connections. A proper crimping tool is used to put the wire into the contact and crimp it, resulting in a safe and dependable connection.

Overall, the SVH-21T-P1.1 socket contact’s design and manufacturing are optimized for dependability, toughness, and use. Due to its distinctive qualities distinguish it from other socket connections, including the dual contact structure and contact spring design, so it is a preferred option for various applications.
