Company Introduction

SART Technology﹐the first Chinese manufacturer of SMD fuse﹐was founded in 2006﹒SART has devoted itself to research and develop circuit protection devices ever since﹒

SART’s facility in Nanjing are certified by TS16949, ISO 9001 and ISO14001﹒Our main products include SMD fuses and Current Sensing Resistors(CSR)﹒ Our SMD fuses have been widely used in different applications like LCD panels、battery packs、battery chargers、digital cameras、cell phones etc﹒

SART ceramic 6125 fuses with raw material originated from Germany have the advantage of a higher breaking capacity﹐facilitating their use in circuits with higher current and voltage﹒Our current sensing resistors(CSR) have great competitive edge in terms of ultra low ohm﹐low TCR﹐tight tolerance﹐high withstanding surge current and low thermal EMF﹒They are designed for current detecting and can be perfectly utilized by intelligent Li-ion rechargeable batteries﹒

With our mission in mind﹐SART has made huge investment in building a strong R&D team﹐a global sales team and an international management team to provide our best service to global customers﹒SART’s mission and commitment are ﹕

S ervice: Global sales offices and on-time delivery

A ffordability: Best quality for best prices available

R ecognition: Win trust and award from major customers

T echnology: Innovative technology for the market

YOU GIVE US AN OPPORTUNITY; WE PROMISE YOU THE FUTURE!

This selection guidelines and product data are intended to provide technical information that will help with selection of fuse. Since these are only a few of the contributing parameters, application testing is strongly recommended and should be used to verify performance in the application circuit.

1. Fuse selection Description

During normal load conditions, the fuse must carry the normal operating current of the circuit without nuisance openings. However, when an overcurrent occurs the fuse must interrupt the overcurrent and withstand the voltage across the fuse after internal arcing. To properly select a fuse the following items must be considered:

➢Application voltage (AC or DC)

➢Normal operating current

➢Ambient temperature

➢Overload conditions and opening times

➢Maximum available fault current

➢Pulse (or Surge current, Inrush current, Start-up current) characteristics

➢Physical size and available board space

➢Standards requirements or environmental protection request

Application Voltage:

The voltage rating of the fuse must be greater than (or equal to) the maximum open circuit voltage Normal operating current: An operating current of 75% or less than rated current of fuse is recommended for operation at 25℃ to avoid nuisance openings.

Ambient temperature:

All electrical characteristics of fuse are rated and validated at an ambient temperature of 25℃.Both higher and lower ambient temperatures will affect the fuse’s opening and current carrying characteristics. Please refer to the temperature derating curve for individual product series found in the specifications.

Overload conditions and opening times:

Specific attention must be given to first overload operating points. For fuses, the first overload point is usually between 200% to 300% of rated current.

Maximum available fault current:

The interrupting rating of fuse must meet or greater than the maximum fault current of the circuit.
