POLY-FUSE Resettable PTCs

Surface Mount > LoRho Series

RoHS

LoRho Surface Mount Series

Description

Littelfuse LoRho Surface Mount PPTC (Polymer Positive

Temperature Coefﬁcient) devices provide overcurrent

protection for applications where ultra low internal

resistance, ultra low voltage drop and automatic

resettable protection are desired. This new series allows

a higher hold current device in a smaller factor and lower

proﬁle as compared to a standard PPTC. It offers ultra

low internal resistance while maintaining the high level

electrical characteristics and performances of standard

PPTC products. All devices are UL recognized and TUV

approved and have maximum fault current of 50A. They

are available in 0402 to 2920 sizes while the hold current

ranges from 100mA to 7A.

Agency Approvals

Littelfuse 0402 size LoRho SMD PPTC is the smallest

size surface mounted PPTC device available in the

market.

WARNING

• Users shall independently assess the suitability of these devices for each of their applications

• Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or ﬁre

•

These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such

conditions are expected to be repetitive or prolonged in duration

• Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices

•

These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses

• Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.

Speciﬁcations are subject to change without notice.
