The PTC range of miniature heaters is positive-temperature-coefficient devices that stabilise rapidly at 100°C-125°C depending on voltage and power rating. With 9mm-high aluminium housing and a flat surface and 200mm wire terminations for easy attachment, PTC heaters are suitable for applications including warming samples or incubating cultures in life-sciences equipment, thermal protection in outdoor electronics cabinets, and condensation prevention for optical equipment such as surveillance cameras. The PTC series comes in two sizes – 20mm x 40mm PTCA devices for 12V/10W and 24V/20W operation and 40mm x 40mm PTCB at 24V/20W and 80-230V/20W.
RTDW wire-wound temperature detectors measure only (0.26” x 0.125”) and offer a choice of radial and axial leaded packages. Positive temperature coefficients from 1100ppm/°C to 6000ppm/°C provide flexibility for temperature measurement and compensation in applications such as industrial temperature probes, aerospace sensors, HVAC controls, and environmental monitors. Standard resistance values are 100Ω, 500Ω, and 1KΩ, in tolerances to ±0.005%.
The RTDS series are surface-mount platinum temperature detectors that are compliant with DIN/EN 60751. The components come in standard AA, A, and B classes for tolerance and temperature range. With high TCR of 3850ppm/°C, the devices combine fast-acting and accurately measurable response, including t0.5 times from 0.1s to 3.3s, with dependable linearity and long-term stability. The halogen-free 0805 and 1206 SMD chip packages allow safe use where flammability is a risk. Standard nominal resistance values are 100Ω, 500Ω, and 1KΩ for measurement current from 1.0mA to 7.0mA.
All three series are available off-the-shelf from Digi-Key
