This level of precision makes these models suitable for applications where small variations in resistance won't disrupt performance. If you're working on a project that demands consistent resistance, this is a key factor to consider.

Power Rating and Load Capacity

The power rating and load capacity determine how much energy the resistor can handle without overheating. For the CFR-25JB-52-1M3 models, the maximum power dissipation is 250mW (0.25W). These resistors are fixed types, meaning their resistance value doesn't change during operation. They also operate within a temperature range of -55°C to 155°C. Here's a breakdown:

This makes them reliable for low-power applications where stability is crucial.

Temperature Coefficient and Stability

Temperature changes can affect how resistors perform, but the CFR-25JB-52-1M3 models are built to handle this. The temperature coefficient (TC) ensures that the resistor's performance remains stable even when temperatures fluctuate. This is especially important if you're designing circuits that operate in environments with varying temperatures. With a stable TC, you can trust these resistors to maintain consistent characteristics, reducing the risk of performance issues.

Material Composition and Durability

The material used in a resistor plays a big role in its durability. The CFR-25JB-52-1M3 models are made of carbon film, a material known for its stability across a wide temperature range. Here's why this matters:

• Carbon film ensures stable resistance, even in challenging conditions.
• It enhances the resistor's reliability in electronic circuits.
• This durability makes it a great choice for long-term applications.

If you're looking for a resistor that can handle wear and tear while maintaining performance, these models are a solid option.

Performance Comparison

Accuracy and Precision

When it comes to accuracy and precision, the CFR-25JB-52-1M3 models stand out for their dependable performance. These resistors maintain a resistance value of 1.3M Ohm with a tolerance of ±5%. This means you can expect consistent results, even if there’s a slight variation in resistance. For most applications, this level of precision is more than enough. Whether you're designing a circuit for consumer electronics or industrial machinery, these resistors ensure your system operates as intended.

If you're comparing them to other models, the difference in tolerance and resistance range becomes a key factor. For example, models with tighter tolerances might offer higher precision but could come at a higher cost. So, understanding this comparison difference helps you choose the right resistor for your project.

Heat Dissipation

Heat dissipation is crucial for any resistor, and the CFR-25JB-52-1M3 models handle it well. These resistors can dissipate up to 250mW (0.25W) of power without overheating. They operate efficiently within a temperature range of -55°C to 155°C. Here's a quick breakdown:

This makes them ideal for low-power applications where heat management is essential. If your project involves prolonged use or fluctuating temperatures, these resistors can handle the load without compromising performance.

Longevity and Reliability

Durability is another strong point of the CFR-25JB-52-1M3 models. Their carbon film construction ensures they can withstand wear and tear over time. They also feature a temperature coefficient of -1500ppm/°C, which helps maintain stability in varying conditions. Here's what contributes to their reliability:

These resistors are also moisture-resistant, making them suitable for environments with high humidity. If you're looking for components that last, these models are a reliable choice for long-term applications.
