# Industrial Specification: Multiplier Circuit

## 1. Technical Definition
Electronic circuit that performs multiplication operations on digital or analog signals.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC input range, 0-10 VDC output range, -40°C to +85°C ambient temperature**. Failure boundary: **Input voltage exceeding 5.5 VDC causes semiconductor junction breakdown, output current exceeding 25 mA induces thermal runaway**, Mechanism: **Semiconductor junction avalanche breakdown at 5.5 V reverse bias, thermal runaway occurs when junction temperature exceeds 150°C due to positive temperature coefficient in bipolar transistors**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
