Product Information

SMD PTC's as Thermal Switches

SMD PTC's as Thermal Switches

Stockcode:

The TPM series of SMD PTC thermistors are frequently used as thermal switches in electronic circuits. Their small size (0402, 0603 or 0805) and step change RT curve (at the trip point) makes these solid-state temperature switches ideal for small spaces and simple to incorporate electronically. Temperature switch points from 65°C to 135°C are available with several R25 (resistance at 25°C) values to suit varying circuit conditions.

About us

UK's leading supplier of thermal components, ATC Semitec specialise in the field of thermal controls. Using our extensive product knowledge, we work with our customers to help them design-in and specify the optimum products from our ranges of NTC thermistors, PTC thermistors, temperature sensors, platinum RTD sensors,  thermostats or thermal fuses.  We carry extensive stocks and distribute circuit protection components such as Semifuse polymer PTC fuses, PEPI thermal cut-outs, SEFUSE thermal cut-offs and Semitec constant current diodes.

Based in Northwich, Cheshire we were established more than 25 years ago and are the UK’s leading thermal component supplier.  We only work with quality suppliers who are some of the leading manufacturers in the thermistor and thermostat industries including Semitec, Heraeus, PEPI, Asahi Keiki, EAW Relaistechnik, Fuzetec, NEC Schott, Matsuo Electric, SEKI & Thinking Electronics.  We operate as a one-stop shop for all your thermal protection needs.

Our range of NTC thermistors and temperature sensors provide high accuracy temperature sensing and control for electronic and programmable thermostats. While our PEPI thermostats, Asahi disc thermostats, Sefuse thermal fuses and bimetal thermal cut-outs offer cost-effective control and over-temperature protection.

Products include NTC Thermistors for temperature sensing, thermal control and temperature compensation; Temperature Sensors for accurate and reliable temperature control with IP67 or IP68 ratings; Bimetal Disc Thermostats for cost-effective temperature control and thermal protection; Thermal Fuses for ultimate product safety with over-temperature protection up to 280deg.C; PTC Thermistors for over-temperature protection and self-limiting PTC heaters; Circuit Protection Devices - Inrush limiters, current regulators, metal oxide varistors; Precision Bi-metal Thermostats - Incomparable performance from an electro-mechanical control; PTC Resettable Fuses - Polymer PTC over-current protection of batteries and circuits; Platinum Sensors - Pt100, Pt500 and Pt1000 elements and IP68 rated temperature sensors.

Our thermal components are readily available from stock for next-day delivery. Please visit the ATC Semitec website for more details or preferably call us for friendly expert technical advice.
