Shop Cornell Dubilier (CDM, CDE) Type 293 High-Voltage Mica Capacitors

A transmitting capacitor built for demanding RF environments, Type 293 handles sustained voltage stress with steady electrical behavior. We stock this series for engineers who require predictable performance during continuous operation. Broadcast, defense, and industrial transmission systems rely on components that hold value under pressure.

Type 293 answers that need through material stability, tight construction, and long service life. We keep inventory ready for fast shipment because downtime costs far more than parts.

About Type 293 Mica Capacitors

Type 293 belongs to a family of mica transmitting capacitors designed for high-power radio frequency applications. This construction uses a layered mica dielectric with metal electrodes. That structure delivers low loss and dependable capacitance across extended duty cycles. Engineers select this series when signal integrity matters during sustained transmission.

High voltage tolerance defines Type 293 performance. These units manage electrical stress without drift that disrupts tuning or efficiency. Many modern systems still depend on this design because alternatives struggle under identical RF conditions. Type 293 continues to perform where other technologies degrade.

Thermal stability remains another defining characteristic. Heat generated during transmission does not compromise dielectric behavior. This trait supports predictable results during long broadcast windows. Engineers value this consistency because recalibration becomes unnecessary. Operational confidence increases across both legacy and modern installations.

Our inventory includes multiple capacitance values within the Type 293 range. We support single replacements and larger procurement needs. That flexibility suits station maintenance teams and manufacturing programs alike. Our technical familiarity helps customers match correct specifications without delays or guesswork.

Benefits of Type 293 Mica Capacitors

Type 293 maintains capacitance accuracy during continuous transmission. This stability protects tuning circuits from drift. Engineers gain predictable system behavior throughout long operating cycles. That reliability reduces service interruptions and improves overall signal quality.

Low dielectric loss reduces internal heating. Less heat means longer component life and reduced surrounding stress. This benefit protects adjacent parts within compact assemblies.

Mechanical strength improves resilience against vibration. Broadcast towers, mobile platforms, and industrial environments introduce movement. Type 293 construction resists physical fatigue. That durability protects electrical integrity during transportation and continuous operation.

Long service life lowers replacement frequency. Maintenance teams face fewer unexpected failures. Planning becomes simpler because parts last longer. That longevity reduces long-term operational expense and service labor requirements.

Compatibility with existing CDM designs simplifies upgrades. Engineers avoid redesign work during replacement cycles. Direct form and function alignment saves time. Systems return to service faster after component changes.
