Type 3322 is a high-strength standoff isolantite insulator engineered for transmitting and RF assemblies that require precise mechanical spacing and dependable electrical isolation. We supply this component to engineers who need predictable performance under heat, load, and vibration without dimensional drift over time. Each unit reflects disciplined manufacturing and tightly controlled specifications.

Our customers rely on us for repeatable quality, dependable availability, and rapid fulfillment. Type 3322 fits applications where clearance, rigidity, and insulation integrity must remain unchanged through long operating cycles. With stocked inventory ready to ship, we eliminate production delays and sourcing uncertainty.

About Type 3322 Mica Capacitors

Type 3322 is a standoff isolantite insulator designed to maintain structural separation while preventing electrical conduction between mounted components. The configuration supports both vertical and horizontal mounting where alignment accuracy directly affects system performance. Standard dimensions include a 1-1/4-inch diameter with a 14-20 tapped thread for secure fastening.

This insulator performs reliably in transmitting equipment, RF systems, and industrial electronic assemblies. The isolantite material resists deformation caused by thermal shifts and mechanical stress. That resistance preserves accurate spacing and protects connected components throughout operation.

We stock multiple length options ranging from 1-1/2 inches through 9 inches. These options allow engineers to specify exact standoff height without modifying surrounding hardware. Each unit meets exact dimensional tolerances, ensuring repeatable installation across new builds and replacement projects.

Benefits of Type 3322 Mica Capacitors

Type 3322 provides rigid mechanical support while maintaining dependable electrical separation. The isolantite body resists cracking, compression, and flexing during installation and operation. This rigidity preserves alignment over extended service life.

Electrical isolation performs reliably in high-frequency environments. The material limits leakage paths and reduces unwanted electrical coupling within RF and transmitting circuits. That performance helps maintain signal clarity and operational consistency.

The 14-20 threaded tap allows secure attachment using standard hardware. Installers achieve firm mounting without excessive torque that could damage surrounding components. This feature shortens installation time and reduces handling risk.

Thermal resistance allows Type 3322 to perform across wide temperature ranges. The material resists expansion and contraction that can loosen fasteners or alter spacing. This behavior helps protect sensitive assemblies from long-term wear.

Multiple length options improve system layout efficiency. Engineers can select the exact spacing required without altering chassis design or component placement. That flexibility improves repeatability across production runs.

Type 3322 also serves as a direct replacement in existing assemblies. Engineers can restore or upgrade systems without redesign or extended downtime, making it well-suited for maintenance and legacy equipment.

Why Choose Commercial Radio Company, Inc.?

We focus exclusively on specialized RF and transmitting components rather than general electronics distribution. That focus allows us to maintain deep inventory, accurate product knowledge, and fast order processing for demanding applications.
