Product catalog summary

Overview: This document provides technical specifications and details for TCS Thin Film Current Sensing Chip Resistors manufactured by Shenzhen KWX Electronics Co., Ltd. It includes information on power ratings, dimensions, features, applications, construction, and performance standards.

Specifications:

Power Ratings: Ranges from 1/16W to 3W at 70°C, depending on the type (e.g., TCS02, TCS05, TCS06, etc.).
Dimensions: Vary by type, with lengths ranging from 1.00mm to 6.35mm and widths from 0.50mm to 6.35mm.
Operating Temperature Range: -55°C to 155°C.
Resistance Tolerance: ±0.5% and ±1%.
Resistance Range: 50mΩ to 1Ω.
Temperature Coefficient of Resistance (TCR): As low as ±50 PPM/°C.

Features:

High power rating up to 3 Watts in 2512 size.
Tight tolerance down to ±0.5%.
Extremely low TCR down to ±50 PPM/°C.
High purity alumina substrate for high power dissipation.

Applications:

Power Management Applications.
Switching Power Supply.
Over Current Protection in Audio Applications.
Voltage Regulation Module (VRM).
DC-DC Converter, Battery Pack, Charger, Adaptor.
Automotive Engine Control.
Disk Driver.
Portable Devices (PDA, Cell Phone).

Construction: The resistors are constructed with an alumina substrate, edge electrode (NiCr), resistor layer (NiCr), bottom electrode (Ag), barrier layer (Ni), overcoat (Epoxy), top electrode (Ag-Pd), and external electrode (Sn).

Performance Standards: The resistors comply with various test methods such as MIL-STD-202 and JIS-C-5201-1, ensuring reliability in insulation resistance, short time overload, endurance, damp heat with load, bending strength, solderability, resistance to soldering heat, dielectric withstand voltage, and thermal shock.

Ordering Information: The document provides a detailed guide on ordering, including type, dimensions, rated power, resistance tolerance, TCR, and resistance values.
