What are the key features of AVB2.3/2/15?
- 2.3 VA power rating with dual 15 V AC secondary outputs for dual-rail supply designs
- Through-hole PCB mounting format simplifies integration into prototype and production boards without adapters
- Dual isolated secondary windings enable split ±15 V DC rails when paired with a full-wave rectifier bridge
What is AVB2.3/2/15 used for?
The AVB2.3/2/15 is designed for low-power embedded power supply stages in audio pre-amplifiers, analog signal conditioning circuits, and instrumentation front-ends that require symmetrical ±15 V rails. Its compact through-hole form factor suits laboratory bench instruments and industrial sensor modules where board space is limited. The dual 15 V AC outputs also make it a practical solution for driving operational amplifier circuits demanding split-rail supply voltages of up to ±21 V DC after rectification.

Frequently Asked Questions
What secondary voltage and power rating does the AVB2.3/2/15 deliver for embedded power supply designs?
The AVB2.3/2/15 provides two 15 V AC secondary windings with a total apparent power rating of 2.3 VA. When combined with a bridge rectifier and filter capacitors, each 15 V winding yields approximately 21 V DC at light load, suitable for dual-rail ±15 V operational amplifier supplies.
How does the dual-output topology of the AVB2.3/2/15 simplify split-rail analog circuit design?
By providing two isolated 15 V AC secondary windings, the AVB2.3/2/15 allows a designer to connect each winding to its own rectifier-filter stage, creating positive and negative 15 V DC rails without a center-tap winding or additional isolation transformer. This dual-output approach reduces component count by at least 1 additional transformer in split-supply instrumentation designs.
What mounting style does the AVB2.3/2/15 use, and how does that influence PCB layout?
The AVB2.3/2/15 uses a through-hole mounting style, meaning its leads pass through drilled PCB holes and are soldered on the opposite side. This provides strong mechanical retention under vibration and simplifies rework compared to surface-mount transformers, making it well suited for prototype runs and low-to-medium production volumes.
For which analog applications is a 2.3 VA PCB transformer the right choice over a higher-rated unit?
A 2.3 VA transformer is appropriate when total secondary load current stays below approximately 77 mA per 15 V winding, which covers most single op-amp circuits, audio pre-amplifier stages, and low-power analog-to-digital converter reference supplies. Choosing a correctly rated transformer avoids excessive core losses and thermal stress that arise when a large transformer runs at very light load.
