Overview of A-Series Chip Attenuator Datasheet
The A-Series Thin Film Surface Mount Chip Attenuator datasheet presents key information on a range of chip attenuators designed by International Manufacturing Services, Inc (IMS). These attenuators are fabricated using a 99.5% alumina substrate and feature nickel barrier layers to support excellent solderability and mechanical integrity. The product is optimized for high-frequency applications, boasting ultra-low noise and stable performance over both temperature and time.
The A-Series attenuators are characterized by low inductance and parasitic capacitance, and are encapsulated with a polyimide passivation layer for enhanced longevity. Suitable for both bulk and tape-and-reel packaging, these attenuators come with a 100% matte tin finish and are RoHS compliant.
Product Specifications
Attenuators in the A-Series vary in rated power from 32 mW to 250 mW at 70°C and are designed with a standard impedance of 50 ohms. The operating temperature range for these components stretches from -55°C up to 125°C. The series adheres to a maximum VSWR of 1.3:1—or 1.5:1 for model A-0402WA—and offers attenuation values ranging from 0 dB to as high as 20 dB for specific models, with tolerances from ±0.3 dB for lower attenuation levels up to ±1.0 dB for the highest.
Performance and Size
The A-Series attenuators maintain their specified performance up to 20 GHz when mounted face down. Different models within the series, namely A-0402WA, A-0603, A-0805, A-1206, and A-1612, vary in size and power ratings. The dimensional outline, indicating length, width, and height, adjusts relative to the model, thus providing a variety of options to accommodate different design needs.
Ordering Information
For ordering, the datasheet outlines a systematic approach using prefixes and part numbers—such as “-0805” for form factor confirmation and appending “O3DB” for denoting 3 dB attenuation—to ensure accurate orders. Attenuation levels and form factors are specified for both face-up and face-down mounting orientations, thus guiding the user to select the appropriate component depending on their assembly requirements.
Contact Information and Certification
IMS, the manufacturer, provides contact details for further inquiries and highlights that the datasheet’s specifications may change without notice. Importantly, the datasheet notes that the A-Series is produced in accordance with ISO9001:2008 standards, ensuring a reliable and quality assured component selection for customers.
