Arrays/Networks Resistors

1. Overview

Resistor arrays/networks are integrated circuits containing multiple resistors in a single package. They provide precise resistance values and spatial efficiency in electronic systems. These components play a critical role in modern electronics by enabling voltage division, signal conditioning, and termination networks while reducing PCB footprint and assembly complexity.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Bussed Resistor Arrays	Common terminal connection for multiple resistors	Digital logic pull-up/pull-down networks
Isolated Resistor Networks	Electrically separated resistor elements	Analog signal conditioning circuits
Voltage Divider Arrays	Precisely matched resistor ratios	Sensor signal scaling in measurement systems
Termination Networks	High-precision impedance matching	High-speed data bus termination
Integrated EMI Filters	Combined resistive and capacitive elements	Noise suppression in communication interfaces

3. Structure and Composition

Typical construction features:

Ceramic substrate (Al O or AlN) for thermal stability
Thin-film or thick-film resistive elements (NiCr, TaN)
Termination pads with Ag/Pd or Sn/Pb metallization
Molded epoxy encapsulation (for discrete packages)
Standard packages: SIP, DIP, SOIC, TSSOP

4. Key Technical Parameters

Parameter	Significance
Resistance Range	0.1 to 10M (determines application suitability)
Power Rating	50mW to 1W per element (thermal management factor)
Tolerance	0.1% to 5% (precision level indicator)
TCR	25ppm/ C to 100ppm/ C (temperature stability)
Insulation Resistance	100M min (isolation performance)
Voltage Rating	50V to 200V (safety and breakdown protection)

5. Application Fields

Consumer Electronics: Smartphones (LCD biasing), IoT devices
Automotive: ECU sensor interfaces, LED lighting control
Industrial: PLC signal conditioning, precision instrumentation
Telecommunications: Transmission line termination, RF circuits
Aerospace: Avionics redundancy systems, navigation equipment

6. Leading Manufacturers and Products

Manufacturer	Key Products
Vishay Precision Group	CRCW-HP series (high-precision thin-film)
Panasonic Electronic Devices	EX-H series (automotive-grade networks)
TT Electronics	WSL series (low-TCR power arrays)
