Heaters
Blow-by, diesel fuel, and diesel exhaust fluid (DEF) heaters from Littelfuse have long ensured vehicles and generators operate in low-temperature environments. Our DEF heater also boosts selective catalytic reduction (SRC) processes. Plus, Littelfuse’s polymeric positive temperature coefficient (PTC) resettable devices heat fluids and gases to improve car battery and digital camera performance.

Recirculating exhaust gas ensures vehicle engines that burn gasoline or diesel fuel do not suffer damage due to the buildup of excess pressure. Heating the recirculating air before it reaches the intake manifold for an internal combustion engine prevents ice crystals from forming and damaging the turbocharger. Littelfuse makes a blow-by heater for this purpose. Our heater consumes very little power and does not require an external thermostat. They also come in sturdy packages that allow them to withstand harsh operating conditions.
- Operates with supply voltages between 8 V and 18 V
- Power rating of 15 W when operating at 12 V
- Operates at temperatures between –40 ℃ and +125 ℃
- Choice of connectors and terminals
- Operates reliably in harsh environments
- Positive temperature coefficients allow heating elements to self-regulate
- Low power consumption eliminates need for external thermostat

Fluid Heaters
Three types of fluid heaters made by Littelfuse perform essential functions in generators and vehicles that burn diesel fuel. Our diesel fuel heaters help keep fuel filters clear by preventing paraffin from dropping out of suspension. We also produce heater modules that combine fuel heaters with water-in-fuel detection and temperature sensors. Last, our DEF heaters stop diesel exhaust fluid from crystalizing into ice particles that could block fuel intakes or reduce the efficiency of selective catalytic reduction (SCR) systems.
- Operate with supply voltages between 8 V and 32 V
- Customizable power ratings up to 250 W at 24 V
- Operate at temperatures up to 130 ℃
- Choice of connectors and terminals
- Positive temperature coefficients allow heating elements to self-regulate
