A-Series Thin Film Surface Mount Chip Attenuator Datasheet

Category: Electronics, International Manufacturing Services Inc, RF Microwave Devices

Overview

The A-Series Thin Film Surface Mount Chip Attenuator is designed and manufactured by International Manufacturing Services, Inc. It is highlighted by features such as a 99.5% Al2O3 substrate material, a nickel barrier layer for improved solderability and mechanical integrity, and ultra-low noise. This component is optimized for high-frequency performance with low inductance and parasitic capacitance, and it retains stable characteristics over varying temperature and time conditions.

Features and Benefits

Polyimide Passivation: The attenuator element is protected by polyimide passivation, ensuring its reliability and durability.

Tape and Reel Packaging: The A-Series is available in bulk or on tape and reel, facilitating automated assembly processes.

Rohs Compliant: The product complies with Rohs standards, which restricts the use of certain hazardous materials in electronic equipment.

Electrical Specifications

The attenuator operates within a temperature range of -55°C to 125°C, and offers a VSWR (Voltage Standing Wave Ratio) maximum of 1.3:1, except for the A-0402WA which is 1.5:1. Performance specification of the A-0805 model maintains character within the scope up to 20 GHz when mounted face down.

Attenuation and Tolerance: Available in attenuation values ranging from 0 to 10 dB, with options of 16 dB and 20 dB for some models, in 1 dB increments with specific tolerances as follows:

A-0402WA & IMS2652: ±0.3 dB (0-3 dB), ±0.5 dB (4-7 dB), ±1.0 dB (8-10 dB)
A-0603 & IMS2533: ±0.3 dB (0-3 dB), ±0.5 dB (4-7 dB), ±1.0 dB (8-10 dB)
A-0805 & IMS1141: ±0.3 dB (0-10 dB)
A-1206: ±0.3 dB (0-10 dB), ±0.5 dB (16 dB)
A-1612: ±0.3 dB (0-10 dB), ±0.5 dB (16 dB), ±1.0 dB (20 dB)

Physical Attributes

Termination styles include full wraparound for A-0402WA & IMS2652 and for A-0603, 0805, 1206 & 1612 IMS1141, IMS2533. The A-Series is available in various sizes, with rated power capacity ranging from 32 mW for A-0402WA & IMS2652 to 250 mW for A-1612, all designed with a standard 50 Ω impedance.

Ordering Information

Ordering information suggests two examples—face up and face down—to illustrate the ordering format, incorporating attenuation level, power rating, and part number.

Note

Specifications are subject to change without notice, and it is recommended to verify the latest version of the datasheet with the manufacturer directly. The company is ISO9001:2008 certified, which ensures a standard of quality for its products.
