PTC Thermistors

PTC thermistor or PTC chip is the heart of all our PTC range heaters, below are some of our standard PTC thermistors available for direct purchase:

Rectangle Type | Disc Type

Features

---

• No Thermostat Required
• Virtually unlimited life
• No moving parts to wear
• Very low cost
• No electrical noise
• The higher the temperature, the more electricity efficient
• Does not burn when in contact with paper, matches or clothes

PTC HEATING ELEMENTS (RECTANGLE TYPE)

---

All models listed in the specifications table below can be portioned into smaller sizes (MIN= 2.5x2.5mm). The resistance of segmented PTC thermistors or PTC chips will increase in proportion with its size.

For example:
1. A PTC chip of 1000Ω, segmented into 1/2, its resistance will become 2000Ω per segment (1000Ω x 2segments = 2000Ω)
2. A PTC chip of 20Ω, segmented into 1/4, its resistance will become 80Ω per segment (20Ω x 4segments = 80Ω)

Typical Applications

---

• Heater Fan
• Heating Plates
• Drying Machines
• Hair Dryer
• Hot melt glue gun
• Foot warmer
• Diesel / fuel heater
• Iron

Rectangular PTC Thermistor Specifications

---

• Models with “◎” symbol in the Specification table are our standard in-stock models, the delivery time for these models is shorter. For non-standard models please contact us for current stock amount before placing orders.
• Voltage, dimension, resistance, temperature, or Curie temperature can also be customized for large quantities. Require 40~60 working days, MOQ of 30K.
• For lower temperature applications (10℃~90℃), please consider our LCHT range products with the characteristics of no inrush current, stable power and follow the Ohms Law. Ratings: 3V AC/DC ~ 600V AC/DC (CUL, CE), T℃=10℃~250℃
• Please note, our PTC elements contain Pb under the permission of RoHS exemption 7(c)-I: Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices, or in a glass or ceramic matrix compound.

PTC HEATING ELEMENTS (DISK TYPE)

---

For low volume round PTC thermistors with unique dimensions, please also consider using rectangular type PTC thermistors with slightly higher temperature for faster delivery and lower MOQ.

For example:
1. A round PTC chip of 8.5mm can be replaced with square PTC chip with 6x6mm (8.5 x 0.707=6.01mm)
2. A round PTC chip of 12.5mm can be replaced with square PTC chip with 8.5x8.5mm (12.5 x 0.707=8.84mm)

Typical Applications

---

• Self control heating elements
• Drying Machine
• Heating Plates
• Carburetor preheating
• Special design for dimensions or Max. surface temperature is also available.
