CRH1206J3R30P05SZ 1206 3.3R 0.5W Ever Ohms Resistor – Functional Overview

I. Product Overview

The CRH1206J3R30P05SZ is a representative model from Ever Ohms Technology’s CRH series of high-power thick film chip resistors. It adopts the standardized 1206 package (metric 3216, body dimensions 3.2mm × 1.6mm), with a nominal resistance of 3.3Ω (3.3R), rated power of 0.5W (1/2W), tolerance of ±5% (J-grade), and a temperature coefficient of ±400ppm/℃. The core design philosophy of the CRH series is to achieve higher power handling capability within a standard package size—upgrading the 1206 package from the conventional 0.25W to 0.5W, effectively doubling the power density.

II. Key Parameters

Package: 1206 (Imperial) / 3216 (Metric), body dimensions 3.2mm × 1.6mm.

Nominal Resistance: 3.3Ω (3.3R), falling within the low-resistance power resistor category, suitable for power circuit applications requiring low resistance values.

Rated Power: 0.5W (1/2W)—this is the key upgrade parameter of the CRH high-power series. Conventional thick film resistors in the same package typically offer only 0.25W, representing a doubled power density.

Tolerance: ±5% (J-grade), meeting the常规 requirements for resistance accuracy in most general-purpose power circuits.

Temperature Coefficient: ±400ppm/℃, ensuring resistance stability across a wide temperature range, with an operating temperature range of -55℃ to +155℃.

Environmental Compliance: Compliant with EU RoHS Directive (2011/65/EU) and free of REACH SVHC substances (1907/2006/EC).

III. Functional Features

High Power Density: The core advantage of the CRH1206J3R30P05SZ 1206 3.3R 0.5W resistor lies in its ability to double the power handling capacity of the 1206 package from the industry-standard 0.25W to 0.5W without increasing PCB footprint. This allows engineers to upgrade circuit power capability without altering PCB layouts.

Thick Film Technology: Manufactured using thick film resistor technology—resistive paste is printed onto a ceramic substrate and sintered at high temperature—offering mature processing, cost-effectiveness, and high reliability.

Surface Mount Design: The 1206 package is highly standardized, compatible with mainstream SMT assembly processes and automatic pick-and-place machines, making it ideal for high-volume production.

Wide Operating Temperature Range: With an operating temperature range of -55℃ to +155℃, it covers industrial-grade application scenarios and maintains stable electrical performance in both high and low temperature environments.

IV. Application Scenarios

The CRH1206J3R30P05SZ 1206 3.3R 0.5W resistor, with its 0.5W power handling capability, is suitable for the following typical applications:

• Power Management Circuits: Feedback networks and load circuits in DC-DC converters and LDO regulators

• LED Driver Circuits: Current-limiting resistors in LED constant-current drivers

• Motor Drive Circuits: Current sensing and current-limiting protection in small DC motors

• Consumer Electronics: Power modules in smart home devices and portable electronic products

• Industrial Control: Power circuits in industrial automation equipment

• Medical Electronics: Power management modules in medical devices
