Low Profile Chip Power NTC Thermistor- SPNT Series
Overview

Sunlord’s SPNT series power NTC thermistors are made of a specially formulated metal oxide ceramic material which can effectively suppress high inrush current surges produced by the turning on of the switch mode power supply.

Background

Design for today's rapidly growing demand for slim power supply, Sunlord’s SPNT series power NTC thermistor can meet the power-conscious, size, cost and reliability targets. Based on multilayer technology and high power NTC material, SPNT series is made with full automatic production lines. Compared with conventional lead power NTC, SPNT series reduce the size as much as 50%, and is the ideal for replacing lead power NTC.

Features

◎ Chip ceramic monolithic structure, small size, strong power and strong capability of surge current suppression

◎ Longevity of service, high reliability, small remain resistance

◎ Big material constant (B value), Fast response to surge current

◎ Excellent solderability, suitable for surface mounted technology

◎ Excellent security, totally composed of fireproof inorganic material

◎ Integral series, extensive operating range

Applications

◎ Slim power supply, slim charger

◎ Conversation Power-supply, switch power, UPS power

◎ Electronic energy-saving lamps, all kinds of electric heaters

◎ LED TV and all kinds of displays

◎ LED lighting and other lighting lamps
