PATIKIL NTC Thermistor Resistors 3Pcs 3Ω NTC3D-20 Inrush Limiter

Description

Product Overview

The PATIKIL NTC thermistor resistors are engineered for high‑sensitivity temperature measurement and robust inrush current limiting. Each unit features a 3 Ω resistance at a standard 25 °C reference point, delivering consistent performance across a wide temperature range. Constructed from a blend of high‑grade metal and engineered plastic, the resistors provide excellent thermal stability and mechanical durability, ensuring long‑term reliability even in demanding industrial environments.

With a maximum steady‑state current rating of 8 A and a dissipation coefficient of 24 mW/°C, these thermistors can safely handle transient overloads while maintaining accurate temperature feedback. The 24 mm pin length and 10 mm pitch allow for straightforward mounting on printed circuit boards or within custom enclosures, making them suitable for compact designs where space is at a premium. The NTC3D‑20 model, identified by its distinctive black coloration, is part of PATIKIL’s extensive thermistor family, recognized for precision and durability.

Usage

These thermistors excel in applications that require rapid response to temperature changes and effective current limiting. Typical use cases include motor start‑up circuits, where the inrush current can be several times the normal operating current, potentially damaging components if not properly managed. By integrating the PATIKIL NTC thermistor, designers can protect motor windings, reduce stress on power supplies, and extend the lifespan of the entire system.

Beyond motor protection, the resistors are ideal for heating elements, air‑conditioning units, electric water heaters, and LED lighting fixtures. Their compact form factor enables installation in tight mechanical housings, while the high‑temperature coefficient ensures accurate monitoring of thermal conditions, facilitating precise control loops in automated systems. Whether used in industrial automation, consumer appliances, or renewable energy equipment, the thermistor delivers reliable performance under varying load conditions.

Installation is straightforward: simply solder the pins to the appropriate circuit points, ensuring correct polarity where applicable. The device operates without the need for additional calibration, providing plug‑and‑play functionality for engineers and technicians. Its robust construction also makes it suitable for harsh environments, resisting moisture, vibration, and temperature extremes commonly encountered in field deployments.

FAQ

What is the temperature range for the PATIKIL NTC thermistor?

The thermistor operates reliably from –40 °C up to +125 °C, providing accurate resistance values across this wide span, which makes it suitable for most industrial and consumer applications.

How do I select the correct model for my circuit?

Choose the model based on the required resistance at 25 °C (3 Ω for the NTC3D‑20), the maximum current your circuit will experience (up to 8 A), and the physical pin dimensions that match your PCB layout. The product datasheet includes detailed tables to guide selection.

Can the thermistor be used for both heating and cooling control?

Yes. Its negative temperature coefficient allows it to increase resistance as temperature rises, making it effective for both heating element regulation and cooling system feedback when integrated into appropriate control loops.

What warranty does PATIKIL provide for these thermistors?

PATIKIL offers a one‑year limited warranty covering manufacturing defects. Should any issue arise, contact our support team with the part number and purchase details for a replacement or technical assistance.

Are there any special handling instructions?

Handle the thermistors with care to avoid bending the pins. Store them in a dry, temperature‑controlled environment. During soldering, use a temperature not exceeding 260 °C to prevent damage to the polymer encapsulation.
